The purpose of this research was to investigate the accumulation of plastic debris in the Wonorejo River Estuary, Surabaya, Indonesia. Visible plastic debris were collected from three (3) sampling points along the intertidal area of Wonorejo River Estuary. The correlation between sampling points (SPs) and the amount of the collected plastic debris (CPD) was analysed using one-way ANOVA. Result of one-way ANOVA showed that the sampling point was significantly affect the amount of the collected plastic debris (p2 from SP1, 375.97±16.72 g dry weight/m2 from SP2, and 291.13±36.28 g dry weight/m2 from SP3. The highest percentage of collected debris item was plastic bags (up to 57.90%), followed by bottle caps (up to 16.65%). The most identified plastic types were Low-Density Polyethylene (LDPE) (up to 73.13%), followed by Polypropylene (PP) (up to 17.22%). Understanding the accumulation of plastic debris in estuary is a fundamental requirement to conduct an advance research related to the marine plastic pollution and to determine further actions to solve this problem. © 2020 The Authors, published by EDP sciences.

The sustainable utilization of biochar produced from biomass waste could substantially promote the development of carbon neutrality and a circular economy. Due to their cost-effectiveness, multiple functionalities, tailorable porous structure, and thermal stability, biochar-based catalysts play a vital role in sustainable biorefineries and environmental protection, contributing to a positive, planet-level impact. This review provides an overview of emerging synthesis routes for multifunctional biochar-based catalysts. It discusses recent advances in biorefinery and pollutant degradation in air, soil, and water, providing deeper and more comprehensive information of the catalysts, such as physicochemical properties and surface chemistry. The catalytic performance and deactivation mechanisms under different catalytic systems were critically reviewed, providing new insights into developing efficient and practical biochar-based catalysts for large-scale use in various applications. Machine learning (ML)-based predictions and inverse design have addressed the innovation of biochar-based catalysts with high-performance applications, as ML efficiently predicts the properties and performance of biochar, interprets the underlying mechanisms and complicated relationships, and guides biochar synthesis. Finally, environmental benefit and economic feasibility assessments are proposed for science-based guidelines for industries and policymakers. With concerted effort, upgrading biomass waste into high-performance catalysts for biorefinery and environmental protection could reduce environmental pollution, increase energy safety, and achieve sustainable biomass management, all of which are beneficial for attaining several of the United Nations Sustainable Development Goals (UN SDGs) and environmental, Social and Governance (ESG). © 2023 The Authors

Quantifying aboveground biomass (AGB) in tropical forests is a challenging but necessary task to support actions to preserve and restore these ecosystems. Recent methods have leveraged the integration of NASA’s spaceborne lidar GEDI with imaging sensors to improve AGB predictions. However, the use of high-resolution (<1 m) stereo images from spaceborne sensors still needs to be explored within these frameworks. The objective of this study was to predict AGB in a tropical forest patch by combining stereo images and GEDI data. A digital surface model (Stereo-DSM) was generated by stereophotogrammetric processing of high-resolution stereo pairs collected from a spaceborne sensor. A canopy height model (Stereo-CHM) was then derived by subtracting an airborne lidar-derived digital terrain model from the Stereo-DSM. Descriptive statistics were calculated from the Stereo-CHM to be used as predictors in the model to predict AGB. We also calculated vegetation indices from the Harmonized Landsat-Sentinel and Sentinel-1 images to compare their relative importance in the model and assess their relationship to the Stereo-CHM metrics. Finally, we trained a Random Forest model using stereogrammetry - derived, multispectral and SAR metrics as features and GEDI’s footprint-level AGB product as a reference. The model to predict AGB yielded performance metrics of r = 0.63, RMSE = 25.38 Mg/ha, and MD = 2.1 Mg/ha. The metrics from the Stereo-CHM were ranked as the most important to the model. This is an indication that these metrics can add important information related to canopy structure to inform GEDI-based models to predict AGB. It is still necessary to evaluate these results considering a variation in canopy cover, topography, and understory vegetation. The findings are important to support advances on the integration of large footprint spaceborne lidar and images with sub-meter spatial resolution to characterize vegetation in tropical forests.

This study developed and evaluated the application of bismuth sulfide doped on graphitic carbon nitride (Bi 2 S 3 @g-C 3 N 4 ) in the degradation of NO under solar irradiation. Bi 2 S 3 @g-C 3 N 4 was prepared through the grinding method. The morphological structure and chemical properties of the synthesized photocatalyst were analyzed before the degradation tests. After doping with Bi 2 S 3 , the bandgap was reduced to 2.85 eV, which increased the absorption of solar light. As a result, Bi 2 S 3 @g-C 3 N 4 achieved higher NO degradation (55%) compared to pure Bi 2 S 3 (35%) and g-C 3 N 4 (45%). The trapping test revealed that electrons were the primary species responsible for most of the NO degradation. The photocatalyst was stable under repeated solar irradiation, maintaining degradation efficiencies of 50% after five consecutive recycling tests. The present work offers strong evidence that Bi 2 S 3 @g-C 3 N 4 is stable and efficient catalyst for photocatalytic oxidation of NO over solar irradiation. © 2022, The Authors. All rights reserved.

This study investigated the simultaneous removal of nitrogen and phosphorus from swine wastewater by a magnesium ammonium phosphate crystallization. The precipitation of struvite was determined from swine wastewater, obtaining the optimal pH, Mg/N/P molar ratio, and reaction time were 9.0, 1.6/1/1.5 and 30 min, respectively. Ammonium and phosphate removal efficiencies were 98.1 ± 0.5% and 98.9 ± 0.4% under optimal conditions, and the highest crystallization mass obtained was 14.6 ± 0.6 g/L. Results illustrated that struvite precipitation is an efficient method for removing ammonium and phosphate in swine wastewater. © 2021 IEEE.

The demand for clean water is increasing due to the increasing population, water pollution, economic development, and climate change. The surfacing of emerging pollutants has put tremendous pressure on the freshwater supply chain. Furthermore, the ineffectiveness of conventional treatment plants in removing these pollutants and adhering to the stringent water quality standards have also increased the troubles in providing safe and clean water to the masses. Thus, advanced water and wastewater treatment technologies are required for fulfilling the growing water demand. Nanomaterials enabled advanced water, and wastewater treatment technologies have shown the potential to deliver clean water. They can also be used to augment water supply by utilizing non-conventional water sources like brackish water and wastewater. Graphene, the wonder material due to its unrivaled physicochemical, electrical, mechanical properties, and functionalization possibilities. Recently, a facile reagent-free method for graphene production was reported using a CO2 laser, termed laser-induced graphene (LIG). Soon after the discovery of this single-step, solvent-free LIG preparation protocol, a plethora of studies have been done across the globe in various fields including, electronics, energy storage, sensors, and water treatment. Here, we have summarized the important LIG studies done in the area of water treatment, which talked about LIG fabrication advancement on a wide variety of carbon substrates for LIG-based filters, membranes, electrodes, and composites for anti-biofouling, antibacterial, pollutant removal, solar thermal distillation, and sensing purposes.
